Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Air Duct Cleaning in Leander, TX
HVAC cleaning in Leander typically runs $350-$650 for a whole-system service, with air quality and sanitizing work adding $200-$450 depending on whether mold treatment or UV light installation is needed. The combination of rapid production-home construction and extreme Central Texas heat means most Leander duct systems carry a unique debris profile: caliche dust from Williamson County limestone soils, construction residue sealed in during build phases, and dense Mountain Cedar pollen loads each winter. CleanRun crews coordinate dispatch from our Austin office and serve Leander homes with the same documented photo record and written upfront pricing we deliver across the metro. Call (737) 252-1285 for a written estimate before any work starts.
Why Leander Homes Are Different
Leander’s housing stock is overwhelmingly young. Ranked among the fastest-growing U.S. cities for over a decade, most homes were built by production builders like D.R. Horton, Meritage, KB Home, and Lennar during active construction phases. Flex ductwork was routinely installed before drywall was finished, with vents left unsealed. That locked caliche construction dust and drywall particulate inside from day one.
The local climate compounds this. Sustained 100°F+ days from June through September push attic temperatures past 140°F, accelerating flex duct liner degradation. Attic-mounted air handlers in communities like Crystal Falls, Bryson, and Travisso pull that heat-stressed air through systems already loaded with construction debris. Then December through February brings Mountain Cedar pollen counts among North America’s highest, turning ductwork into a direct vector for one of Texas’s most notorious allergen events. Technicians in Bryson’s newer sections regularly find 2-3 year old homes with ducts coated in white caliche dust from adjacent graded lots combined with original construction residue. “New” here does not mean clean.
Our Main Leander Services
Leander homeowners most often call us about these three services, each with its own dedicated Leander page and documented approach.
Air Duct Cleaning in Leander
We clean the full duct network: supply and return runs, trunk lines, plenum (the main distribution box), and registers. In Leander, this means addressing the specific debris profile locked in during construction phases, plus seasonal pollen loads. Every run is photographed before and after, and the written scope is delivered before any panel comes off. Air Duct Cleaning in Leander covers full pricing and what’s included.

Dryer Vent Cleaning in Leander
Lint accumulation in dryer vents is a fire hazard and efficiency drain. In Leander’s newer subdivisions, longer vent runs through exterior walls are common, increasing blockage risk. We use rotary brush systems and negative-pressure extraction to clear the full line, then photograph the interior condition. Dryer Vent Cleaning in Leander details our process and flat-rate pricing.

Duct Repair & Sealing in Leander
Leander’s extreme attic heat degrades flex duct insulation and separates connections at elbows and collars. We repair torn liners, reseal connections with mastic (a thick, permanent sealant), and replace degraded sections. Every repair is photographed and the written scope agreed before work begins. Duct Repair & Sealing in Leander explains when repair beats replacement.

Before
AfterHVAC Cleaning in Leander

Leander’s climate and housing stock create a specific maintenance profile: attic air handlers running 3,000+ hours annually through heat-degraded flex duct, pulling caliche dust and construction debris past coils and blowers that were never designed for that particulate load. The result is reduced airflow, frozen coils, and compressor strain that shows up in July, not January. HVAC Cleaning addresses the full system, not just the ducts.
Evaporator Coil Cleaning
Signs you need it
Ice on the coil, weak airflow from registers, or the system running continuously without reaching set temperature.
What it costs in Leander
Evaporator coil cleaning in Leander typically ranges $180-$320.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph before and after condition.
Blower Cleaning
Signs you need it
Unbalanced airflow between rooms, vibration noise from the air handler, or dust puffing from registers at startup.
What it costs in Leander
Blower assembly cleaning in Leander typically ranges $150-$280.
How we do it
We remove the blower wheel and housing, clean blades and motor housing with compressed air and solvent, balance the assembly, and document with photos.
What HVAC Cleaning Costs in Leander
| Item | Typical range in Leander |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower assembly cleaning | $150-$280 |
| Full HVAC cleaning (coil + blower + cabinet) | $350-$650 |
How do I know my HVAC needs cleaning versus just the ducts?
If your ducts are clean but rooms still heat unevenly, the system runs long cycles, or you see ice on the coil in summer, the problem is likely in the air handler components. We inspect the coil and blower during every duct cleaning and will show you the photo evidence before recommending HVAC cleaning.
Can HVAC cleaning fix my high summer electric bills in Leander?
Dirty coils and blowers force the system to run 15-30% longer to move the same air; cleaning restores designed efficiency. We measure static pressure before and after to document the improvement, and the photo record shows exactly what was restricting airflow.
Air Quality & Sanitizing in Leander

Leander’s Mountain Cedar season delivers pollen loads that standard filtration cannot capture, and the combination of construction debris plus summer humidity in attic ductwork creates conditions for microbial growth. Air quality and sanitizing targets what cleaning alone cannot remove: living contaminants and persistent odors. Air Quality & Sanitizing covers the full range of treatments we offer.
Mold Treatment
Signs you need it
Musty odor when the system runs, visible spotting on registers or duct liner, or allergy symptoms that worsen at home.
What it costs in Leander
Mold treatment in Leander typically ranges $300-$550.
How we do it
We apply EPA-registered antimicrobial through the duct system using fogging equipment, treat affected surfaces, and verify with post-treatment photos.
UV Light Installation
Signs you need it
Recurring microbial growth after cleaning, high allergy sensitivity, or a home with chronic moisture issues in the HVAC cabinet.
What it costs in Leander
UV light installation in Leander typically ranges $400-$750.
How we do it
We mount a UV-C lamp in the supply plenum, wire to the blower circuit for automatic operation, and provide the model specification for independent verification.
What Air Quality & Sanitizing Costs in Leander
| Item | Typical range in Leander |
|---|---|
| Mold treatment | $300-$550 |
| UV light installation | $400-$750 |
| Full air quality package (treatment + UV) | $600-$1,100 |
Does UV light actually work against Mountain Cedar pollen?
UV-C lamps target mold spores and bacteria, not pollen; for pollen, we pair UV with upgraded filtration. We specify the filter MERV rating and photograph the installed configuration so you can verify what you’re breathing through.
How do I know mold treatment was actually done?
Every treatment is photographed before and after, with the antimicrobial product label visible in the job record. We deliver these photos as part of the standard documentation, not upon request.

FAQs About Air Duct Cleaning in Leander

No permit is required for standard cleaning or sealing. Duct modifications that alter the HVAC footprint may need Williamson County review; we flag this during the initial inspection and include any permit requirements in the written scope before work starts.
